Kyosho UMW708-11 1.1mm Rear Stabilizer Bar Pink

This is the 1.1mm rear stabilizer bar for the Kyosho Ultima RB6 in mid-motor configuration, supplied as a single bar. A stabilizer bar, also called an anti-roll or sway bar, links the left and right suspension arms so that when one side compresses in a corner the bar resists the chassis rolling over onto that side.

At 1.1mm this is the softest bar in the four-bar UMW708 series. A thinner bar allows more body roll and lets weight transfer across the axle more gradually, which builds mechanical grip at the rear. That makes it the bar to reach for on rough, loose, dusty or freshly watered tracks where the buggy needs forward bite and the suspension needs freedom to follow the surface.

Stiffer bars in the same series do the opposite, cutting roll and sharpening direction changes for high-bite indoor clay and blue-groove astroturf. This is a service bar for the optional UMW708 rear stabilizer set, which must already be installed on the buggy. Fits the Ultima RB6 and RB6.6 in the mid-motor layout, and dealers also list it for the Ultima SC6.
